Honestly, this is what I consume here in my home according to per hour based on kWh. So I think, I supposed to
expect a high cost for the electricity for the first month I guess. But I will observe it for the first trial as of the moment.
$0.18/kWh is definitely bad electricity rate for mining. Even if you use Antminer S19 XP Hyd (255Th) which have best energy efficiency[1], your profit is very small[2] and you'll not reach break even before more efficient ASIC comes out.
